$40 cash app if you can diagnose

Hello,

I'm growing in a greenhouse with LED,s.
Coco 70/30 mix with perlite.
Mills Nutirents. With calmag+, superthrive, and photosynthesis plus.

Temps 77-83
Humidity 45-55%

Its showing on a few strains. Starting on new growth. Bronze/plae brown in color. Started as small freckles.

Help is well appreciated. If you can diagnose it with some evidence. I'll cashapp you $40.

Are u phing?

Definitely a Ca deficiency, probably a K and Mg deficiency as well. This would be easier if all pictures were in natural light. You might also have a little to much N (again a guess because of the lights).

The Ca is orange punctate rust spots first image
The K is the brown on the edges of lower leaves first image (med to lower left)
The Mg is interveinal chlorosis in the second and last image

PS I grow in 50/50 coco/perlite here's a couple of the girls I should be upstairs killing instead of shooting the shit here. Best of luck on your grow.

Have you checked the underside of your leaves? Is there a possibility you have any bugs?

I’d start by checking your effluent,looks like it’s been over fed,could be too much potassium,as coco readily gives it up,and if your not using coco specific nutrients it could lead to problems..

Those are very nice. Now, if you could just tell people how to do that, things would be golden. The weird thing about these forums is there isn't one that says "hey, I've done great and this is how I do it." It would be the only thread people need to read.

Yes the spots appear to start in between the vains,Mg.My advice is listen to this gal,provide alll the info with natural light pics.

I can't do that because there isn't one way to grow. We grow in a myriad of different ways and they can all end up great. Most of us learn by trial and error and me writing someone can be misunderstood. So it's a game of trial and error. Thanks for your kind words about my plants.

Thank you that is very kind.

It appears, as Curious2Garden has suggested, you're short on Ca. This may be a result of a bad pH, too much of other nutrients locking it out or it's non existent. This is where I'd start. Good luck.

Yeah first look for bugs...very tiny underside of the leaves. What kind of water you using? RO may need to add cal mag. . Also with using LED plants need extra calcium. Try switching to mh or hps

ROFLMAO!! Nope, but today I chopped her next door neighbor. She's giving me the stink eye. She'll be dead before Sunday (I hope).

oh man, thats going to smoke great with how long you let her go. I like to let them run long and get that heavy amber going.

Thanks, I think she's only in her 11th week. 12 would start Monday. Her trichomes are mostly cloudy with some clear and a few amber. She could go longer.

I say to much nute, my buddy says check for bugs. So that we were are over here.
Good luck buddy you will get it figured out

Nutes are definitely a problem...Ca, Mg K..that curling up of leaves can indicate a potassium deficiency...(if not to close to the lights)

pH can cause issues with uptake of nutrients..calcium tends to be more effective over a pH of 6.5...

That said, all of that fine spotting on the leaves gives me the impression some "we beasties" are having a nibble too...

I was wanting you to describe your way of getting plants that healthy. It isn't a matter of different ways to grow. I wanted you to describe your way. It's not for me, but for others who could use some help. But meh, whatever....
I don't see how anyone can say it's nutrient def, like calcium, because the OP wrote this:
I'm growing in a greenhouse with LED,s.
Coco 70/30 mix with perlite.
Mills Nutirents. With calmag+, superthrive, and photosynthesis plus.

How can anyone tell that the spots are a particular color when it looks like the light is purple? On the spot color, the OP wrote this:
Bronze/plae brown in color
The most frequent I see take place is lake of accurate diagnosis. You can't have Ca def when calcium is given. Some will say bad pH will screw up Ca. Maybe so, but then that's the problem-- the pH issue. Find the cause of that and fix it first.
Frankly, I don't know what the problem is with those plants, but making the wrong assessments will lead people down the wrong road. With all the stuff being given, my bet is going to be that the fert load is too much, especially since the OP failed to write exactly how much and how often are the feedings.

The answer is quite simply her years of experience and paying attention to her plants.
Thats not something you can really teach.
